Application Of Hard Anodic Oxidation

We know that the stove fan is required for heatconduction to work ,and the highest temperature part of heat conduction which is the under support frame of the stove fan, also the base. Although the aluminum alloy has a very high strength, and we also carried out its ordinary anodizing treatment

But as the highest part of the stove fan, long hours of high temperature work, some stove burned even more than 250℃. Considering such extreme conditions, we need to be a separate strengthening treatment for stove fan.

We use hard anodizing on the lower bracket this craft can be formed on the surface of a layer of thickness of 25-150µm alumina coating, and further improve the strength of aluminum,wear resistance and corrosion resistance. Link has lot of year of experience in the manufacture of stove fans, and now the stove fan that we manufacture the oxide film are between 50-80µm. This direct performance is that our lower bracket can work up to 350℃ on the surface of the stove, the brackets do not have any problems, even the color of the coating will not change!

And some stove fans, if the craft is poor, the phenomenon may occur discoloration when the temp. up to 300℃, If the temperature continued to rise, may caused deformation and other serious problems.
